[pt] MEDIDAS DE RÁDIO PROPAGAÇÃO EM UHF EM AMBIENTES SUBURBANOS PARA TV DIGITAL: ESTUDO DE COBERTURA PARA RECEPÇÃO FIXA / [en] UHF RADIO PROPAGATION MEASUREMENTS IN SUBURBAN ENVIRONMENTS FOR DIGITAL TV: STUDY OF COVERAGE FOR FIXED RECEPTION

JOAO FELIPE BUENAGA CAVALCANTI 28 December 2005 (has links)
[pt] A previsão da perda de propagação na faixa de UHF tem grande importância para o dimensionamento dos sistemas de TV Digital. Com base em uma grande campanha de medidas na cidade do Rio de Janeiro pretende- se, com esse trabalho, descrever o comportamento do sinal, assim como verificar a existência de modelos adequados para caracterizá-lo. / [en] Methods for prediction of propagation loss in the UHF band have great importance for the Digital TV systems sizing. With basis of a great measures campaign in Rio de Janeiro city, this work intendeds to describe the behavior of the signal end to verify the existence of adjusted models to characterize it.
